Questions and Answers

What is homeostasis and why is it important in animal physiology?

Homeostasis is the regulation of the internal environment of an organism despite external changes, ensuring stable conditions essential for survival.

Describe the role of natural selection in the process of evolution.

Natural selection is the mechanism by which individuals with advantageous traits are more likely to survive and reproduce, leading to changes in the traits of a population over generations.

What are the primary processes involved in photosynthesis?

Photosynthesis primarily involves the conversion of light energy into chemical energy through processes like the light-dependent reactions and the Calvin cycle.
